Professional rebuilding and modernisation of a Sakamura BPF-540 multistage cold forming press, built in 1991
In addition to the rebuilding of the Hatebur AKP 4-5 the focus laid on the Sakamura machine – besides the rebuilding – was modernisation.
In addition to the brand new electrics S7-300 PLC make, we replaced seven standard motors – five motors for the ejector stroke adjustment, one for the length stopper and another one for the feeding length – by modern servo motor systems. We changed the support for the servo motors and integrated the system into the machine control. Nowadays, a tool data system makes it possible to recall all tool information requested to minimize tool setting time.
A blank stopper has been designed for short blank parts or tapered shafts such as ball joints. A transfer camshaft with hydraulically actuated transfer cams has been designed for this machine.
